First embodiment
Referring to fig. 1, in the present embodiment, a reverse-connection preventing charging apparatus 10 is provided, which can be used for charging a rechargeable battery (not shown), and it should be understood that the reverse-connection preventing charging apparatus 10 can also be used for supplying electric power to an electric appliance. The reverse connection preventing charging device 10 provided in the present embodiment can prevent the rechargeable battery from being damaged due to the reverse connection of the rechargeable battery. It should be noted that the reverse connection prevention charging device 10 can also be used for reverse connection prevention power transmission of electrical appliances for distinguishing positive and negative poles.
The reverse-connection preventing charging apparatus 10 includes a charger 100 and a reverse-connection preventing circuit 200. Wherein the charger 100 is electrically connected to the anti-reverse connection circuit 200. The charger 100 is used for supplying power to the rechargeable battery, and the reverse connection preventing circuit 200 is used for disconnecting the electrical connection between the charger 100 and the rechargeable battery when the rechargeable battery is reversely connected, so as to prevent the rechargeable battery from being damaged due to the reverse connection.
The rechargeable battery has a positive electrode and a negative electrode, and when the rechargeable battery is charged, current flows into the rechargeable battery from the positive electrode of the rechargeable battery to charge the rechargeable battery.
The charger 100 has a positive connection 110 and a negative connection 120 for outputting power. The positive connection 110 is used to connect to the positive electrode of the rechargeable battery, and the negative connection 120 is used to connect to the negative electrode of the rechargeable battery. Here, the reverse connection of the rechargeable battery refers to that the positive electrode connection 110 is connected to the negative electrode of the rechargeable battery, and the negative electrode connection 120 is connected to the positive electrode of the rechargeable battery. Accordingly, when the positive connection 110 is connected to the positive terminal of the rechargeable battery, the negative connection 120 is connected to the negative terminal of the rechargeable battery indicating that the rechargeable battery is connected.
The reverse connection preventing circuit 200 has one end connected to the positive connection line 110 and the other end connected to the negative connection line 120. And, the anti-reverse connection circuit 200 is provided with a one-way conduction element 210, the one-way conduction element 210 can conduct one-way conduction to the anti-reverse connection circuit 200, and enable current to flow from one end of the anti-reverse connection circuit 200 close to the positive connection 110 to one end of the anti-reverse connection circuit 200 close to the negative connection 120. In addition, a relay coil 220 is also provided on the reverse connection preventing circuit 200.
Further, a relay switch 111 is provided on the positive connection 110, and the relay switch 111 is matched with a relay coil 220 on the reverse connection preventing circuit 200. When the relay coil 220 is energized, the relay coil 220 can generate magnetism through electric energy, and further attract the relay switch 111 to be closed, so that the conduction of the positive connection wire 110 can be realized.
Also, in the present embodiment, the relay switch 111 is provided between the anti-reverse connection circuit 200 and the charger 100. That is, the positive connection 110 is provided with the relay switch 111 and the reverse connection preventing circuit 200 in this order from the end near the charger 100 to the end for connecting the rechargeable battery.
It should be understood that in other embodiments, the relay switch 111 may also be disposed on the negative connection 120, when the relay switch 111 is disposed on the negative connection 120, the relay switch 111 is also located between the charger 100 and the anti-reverse connection circuit 200, i.e., the negative connection 120 is disposed on the one end of the rechargeable battery for connecting the relay switch 111 and the anti-reverse connection circuit 200 from the end near the charger 100 to the end of the negative connection 120.
The principle of the reverse connection prevention charging device 10 for preventing the reverse connection of the rechargeable battery is as follows:
when the positive pole of the rechargeable battery is connected to the positive connection 110 and the negative pole of the rechargeable battery is connected to the negative connection 120. At this time, the rechargeable battery, the end of the positive connection wire 110 close to the rechargeable battery, the reverse connection preventing circuit 200, and the end of the negative connection wire 120 close to the rechargeable battery form a closed loop together, so that the rechargeable battery can provide electric energy to the relay coil 220, and at this time, the relay coil 220 obtains the electric energy to generate an attraction effect on the relay switch 111, so that the relay switch 111 is closed and the positive connection wire 110 is conducted. When the positive connection 110 is conductive, the charger 100 provides power to the rechargeable battery.
When the positive pole of the rechargeable battery is connected to the negative connection 120 and the negative pole of the rechargeable battery is connected to the positive connection 110. At this time, since the unidirectional conducting element 210 can only flow current from the end of the reverse connection preventing circuit 200 close to the positive connection 110 to the end of the reverse connection preventing circuit 200 close to the negative connection 120, no current passes through the reverse connection preventing circuit 200 due to the blocking of the unidirectional conducting element 210, the relay coil 220 is not powered, the relay switch 111 cannot be closed, the positive connection 110 can be disconnected, and the rechargeable battery can be prevented from being charged. The reverse connection prevention of the rechargeable battery is realized in the above mode, and the damage of the rechargeable battery caused by the reverse connection of the rechargeable battery can be avoided.
Alternatively, in the present embodiment, the one-way conduction element 210 is disposed between the positive electrode wiring 110 and the relay coil 220. That is, when a current flows from the end of the reverse connection preventing circuit 200 near the positive connection 110 to the reverse connection preventing circuit 200, and a current flows along the reverse connection preventing circuit 200 to the end of the reverse connection preventing circuit 200 near the negative connection 120, the current passes through the one-way conduction element 210 and the relay coil 220 in order. With this arrangement, it is possible to prevent the relay coil 220 from being directly connected to the positive connection wire 110 of the charger 100, so that the relay coil 220 is damaged by directly inputting excessive electric power to the relay coil 220 when the positive connection wire 110 is turned on.
In addition, in the present embodiment, the unidirectional conducting element 210 may include a diode or a MOS transistor.
Further, in the present embodiment, the reverse connection preventing circuit 200 is further provided with a prompting device 230, and the prompting device 230 is connected in series with the unidirectional conducting element 210. That is, when the unidirectional conducting element 210 conducts the anti-reverse connection circuit 200, the prompting device 230 is powered on, and the prompting device 230 can send a prompting signal to an operator after being powered on, so that the operator can know that the current operation is the correct operation. When the rechargeable battery is reversely connected, no current passes through the reverse connection preventing circuit 200, the prompting device 230 is not powered, a prompting signal is not sent, and an operator can know that the charging connection mode of the rechargeable battery is currently reverse connection. It should be understood that when the prompting device 230 does not send the prompting signal, the prompting device 230 may have a fault, so the condition for determining the reverse connection of the rechargeable battery by the prompting device 230 is the normal operation state of the prompting device 230.
Optionally, in the present embodiment, the prompting device 230 is disposed in parallel with the relay coil 220. When the anti-reverse connection circuit 200 is turned on, current flows to the relay coil 220 through the one-way conduction element 210 and to the indication device 230. The prompting device 230 can provide a shunt function for the relay coil 220 to avoid an excessive current in the relay coil 220.
It should be understood that in other embodiments, the prompting device 230 may be connected in series with the relay coil 220, where the prompting device 230 can provide a voltage dividing effect to the relay coil 220. It should be appreciated that the operator can select the connection between the notification device 230 and the relay coil 220 according to actual needs.
The prompting device 230 may include a sound prompter or an indicator light.
The charger 100 further has two input connections 130, and the two input connections 130 are used for connecting a live wire and a neutral wire, i.e. the arrangement of the input connections 130 enables the charger 100 to receive commercial power and transmit the commercial power to the rechargeable battery through the positive connection 110 and the negative connection 120 after being processed. The processing of the utility power may include voltage reduction or rectification, and is all the prior art, and is not described herein again. It should be understood that the input lines may be connected to the positive and negative poles of other batteries as well.
In addition, the charger 100 further includes a grounding wire 140, and the grounding wire 140 is used for grounding to ensure the use safety of the charger 100.
In summary, the reverse connection preventing charging device 10 provided in this embodiment can control the power of the relay coil 220 through the unidirectional conducting element 210 on the reverse connection preventing circuit 200 disposed between the positive connection line 110 and the negative connection line 120, when the positive connection line 110 is connected to the positive electrode of the rechargeable battery and the negative connection line 120 is connected to the negative electrode of the rechargeable battery, the rechargeable battery can provide power to the relay coil 220 through the reverse connection preventing circuit 200, and the power of the relay coil 220 turns on to close the relay switch 111, so that the positive connection line 110 of the charger 100 and the positive electrode of the rechargeable battery can be conducted, and the rechargeable battery can be charged. When the positive connection wire 110 is connected to the negative electrode of the rechargeable battery, at this time, since the one-way conduction element 210 cannot conduct the reverse connection prevention circuit 200, the relay coil 220 cannot be powered, and the relay switch 111 cannot be conducted, so that the rechargeable battery can be prevented from being supplied with electric energy when the rechargeable battery is reversely connected, and the situation that the rechargeable battery is damaged due to reverse connection of the rechargeable battery is further prevented.
Second embodiment
In the present embodiment, an electronic device (not shown) is provided, which uses the reverse connection prevention charging apparatus 10 provided in the first embodiment, and which can charge the rechargeable battery and can prevent the rechargeable battery from being damaged due to reverse connection.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
